防雷工程是一项系统工程，要求将外部防雷装置和内部防雷装置统一考虑，着眼于全方位的雷电综合防护，把机房建筑物的防雷、雷电电磁脉冲（LEMP）防护、设备防雷、电源系统防雷、线路防雷、接地系统、保护装置等综合因素考虑在内。任何方面的遗漏带来的危害都是不能(Mine is a systems engineering project, requiring the external and internal lightning protection lightning protection devices to consider a unified, integrated focus on the full range of lightning protection, lightning protection of buildings to the engine room, lightning electromagnetic pulse (LEMP) protection, equipment, anti- Thunder, lightning protection power system, line lightning protection, grounding systems, protective devices and other comprehensive factors into account. Omission of any harm is not)

本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF(This paper describes the principle of DTMF and how MATLAB to generate DTMF signals, mainly related to the telephone dial tone and identification of the basic principles of synthesis of the main method, using MATLAB software, and the FFT algorithm to the telephone communication system, the synthesis and identification of dial tone . And further the use of MATLAB' s graphical user interface simple and intuitive GUI make the analog interface. Able to use a different fundamental frequency matrix synthesis of 0- 9 different button dial tone and can be different correct identification of dial tone to achieve by the dial tone of the process of parsing a telephone number to complete the telephone dial tone system, a simple experiment simulation.-This paper described the principle and how DTMF in MATLAB to generate DTMF)
